To Treblig---I never could have imagined when I ask the original question of "whether the floor linkage could be made to work with a 200r4" that it would turn into such a great thread. Thank you for a lot of us for making this so complete and detailed. I am at this point completely jealous that you have yours completed. Now I am looking forward to jbc426 reporting on his build using the powerglide bellhousing. I would like to report more progress on my own 68 Dart convertible but still am not rebuilding yet. I have though, at this point purchased a Buick Grand National 200r4 that I will be using when the time comes.
I do still have a lingering question. You have no doubt proven that the floor shift linkage can be re-engineered to work. My question is for us average Joe's without a lot of fabrication skills. (drum roll) Looking back would it be easier to use a cable linkage with the floor shifter? Would a cable be a little more forgiving on the flex and rotation of the driveline vs such short fixed linkage? Your thoughts would be appreciated. If I recall you had moments thinking about this as a backup but you were always able to engineer your way to a solution. Once again thank you for staying the course with both your pictures and explanations.
